Engineering Commitment
Every line is engineered against a written performance specification. Line speed, cure profile, film build and emission level are stated in the contract and demonstrated on your own part at the factory trial run before shipment. One engineering team owns the whole chain — pretreatment, application, curing, conveying and emission control — so the trade-offs between them are settled on the drawing board, not on your factory floor.
Service & Delivery
Standard configurations ship in 30-60 days with 12-24 months warranty. On-site installation, commissioning and operator training are available worldwide, and process tuning and spare parts support continue for the working life of the line.
